[PATCH] checkpatch: Update "Missing a blank line after declarations" test

From: Joe Perches
Date: Sat Mar 22 2014 - 19:22:20 EST


"struct foo *bar" does not match the regex "$Declare\s+$Ident"
$Declare matches "struct foo *" but there is no required space
between the pointer "*" and the $Ident.

Also it ends in a pointer, the $Declare variable also contains all
trailing spaces after the declaration so there is no space between
$Declare and $Ident.

ie: "struct foo * bar" does not match "$Declare\s+$Ident"

So, change the \s+ to \s* to have this regex match any of
"struct foo bar", "struct foo *bar", and "struct foo * bar"
